Abstract

Cette invention concerne un appareil destiné à monter un équipement ou des structures solaires photovoltaïques sur des toits, le socle (214) de l'appareil venant directement en prise avec la surface du toit de façon à créer un joint résistant à l'eau, sans qu'il soit nécessaire d'utiliser des éléments de calfeutrage. La surface supérieure dudit socle (214) comprend une partie faisant saillie vers le haut (304) qui est circonscrite par une rainure (314). La surface inférieure du socle (214) comprend un lamage (406). Ledit lamage (496) et ladite rainure (314) sont tous deux disposés de façon à recevoir des joints annulaires. Un élément de fixation fileté (212) est reçu et supporté par la surface supérieure de la partie faisant saillie vers le haut (304) et il est introduit à travers le lamage (406) de façon à fixer le socle (214) à la structure de toit et à créer un joint résistant à l'eau en comprimant le joint annulaire inférieur (332) et en créant un contact de surface à surface avec le toit et une partie du socle (214). Une partie de couverture à filetage intérieur (334) vient en prise avec la partie faisant saillie vers le haut (304) directement ou à travers une pièce intermédiaire, de façon à créer un joint résistant à l'eau au-dessus de la pièce de fixation (212).
